A gunman killed one person before killing himself on Friday night at a yoga studio in Tallahassee, Florida's capital, police said.

Six people are in the hospital.

Tallahassee Commissioner Scott Maddox says it's the worst scene he's witnessed.

Police received a call at 5.37 pm of a shooting at the Hot Yoga Tallahassee studio and found multiple gunshot victims when they arrived at the small shopping center where it is located, city Police Chief Michael DeLeo told reporters.

"The suspect is deceased and one victim has passed away at the hospital," he told reporters.

The gunman appeared to have acted alone and there was no immediate threat to the Tallahassee community, DeLeo said.

He gave no motive for the attack or details about the shooter.
